style="font-family:宋体;">土壤重金属污染修复问题一直是环境污染处理的重难点，因为重金属离子一般不具备生物降解性，并能通过食物链等途径进入生物体进行富集，对人身体健康影响极大。目前的处理方法主要有生物（植物）富集法，受制于生物体筛选和生长时间长等原因，不适宜快速治理，另一类是物理化学法，利用各类吸附剂开展重金属污染的快速治理，依据吸附剂的物质组成，可分为有机型吸附剂和无机型吸附剂两大类。今天就来谈谈中凯<a href="http://www.xyzkbw.com">改性珍珠岩</a>对重金属离子的吸附效应。<br /> 通过中凯珍珠岩实验室分析结果发现，通过改性后的中凯<a href="http://www.xyzkbw.com">珍珠岩</a>对重金属的吸附效果明显高于未改性珍珠岩。吸附剂对重金属的吸附能力与重金属离子的电价、半径、有效水合半径、水化能等有关，改性后对于重金属吸附速率，较快达到吸附平衡。改性后吸附剂表面的珍珠岩内部的孔隙结构和比表面积增大，活性位点得到充分应用，吸附容量大幅度提高。<br />
